Windows does bitlocker and works pretty well. Depending on what you’re trying to do this may be a good solution.

Windows will use more resources idling than anything Linux, or purpose built will. You can do anything with windows as it turns out. After reading in r/homelab you might think, wow, no one runs a server on windows, which couldn’t be farther from the truth. TONS of enterprise runs on windows, and almost ALL small businesses runs on windows. It’s easy, simple, and there’s a cost for that. Windows Server is a purpose built windows version for being a server, there’s some more management built in, but really, at it’s core, windows 10/11 pro will do just fine for home use.
